Hydraulic Press Brakes- All You Need To Know

Jul 16th 2015 at 1:52 AM

In the manufacturing industry, three kinds of press brakes are commonly used. These are:

· Pneumatic

· Hydraulic

· Mechanical


The mechanical varieties operate with crank mechanism in compartment with the wheel energy drive. Hydraulic and pneumatic presses respectively utilize hydraulic oil and air pressure as their energy source. In sheet metal cutting and manipulation, the use of pneumatic presses is quite limited restricted mostly to industrial sites for production processes requiring minimal efforts. Nowadays, hydraulic CNC press brake is quite common in the manufacturing processes especially with its computerized controls that ensure quicker and more accurate results. The various parameters characterizing the hydraulic presses are as follows.


· Working length, force

· Distance between frame uprights

· Amplitude

· Work piece support

· Additional accessories for enhancing production

· Compensation device deflection table


In the past, pneumatic and mechanical presses were most commonly available in various industries. As the requirements of various enterprises increased with time, hydraulic presses came to the forefront and have been dominating since then. The advantage of such press brakes over the other types is easy to see. Quality of the products manufactured has improved significantly with lowered injury risk, high reliability, and low consumption of energy. Companies that are unable to invest in brand-new machines go for used press brake from leading brands to experience the associated benefits.


Nowadays, the press brakes come with state of the art features and safety mechanisms that increase their usability further. These features include the following:

· Graphical UI, automatic calculation of operational bending sequence

· Additional hardware use

· Operator control protection devices

· Sensor monitoring of received bending angle

· Overload protection, and more

So how do the hydraulic presses work?

These presses adjust upper crossbeam status and during pressing the two-handed button or pedal control starts moving downwards at fixed speeds that is higher than direct bending. Computerized regulations these days fix the associated speed and keep it within a certain range as decided by the operator. Once it reaches the switching speed, point shifting of system control towards lower speeds occurs. At the point of switching, speed synchronization occurs simultaneously along with the movement of right and left hand cross. Signals reach the hardware management automatically for required adjustments.

Once the speed changes happen, movements traverse towards the dead centre. How everything happens will determine the quality of the products manufactured. The main application of hydraulic press brakes is in folding and bending of metal after pressing it inside a die. They are used in both production of continuous applications and sheet metal specialized work. Their application is possible in cell automated components and single-cycle operations as desired by the manufacturers. Many presses come with extensive networking function and bending capacities utilized for pre-coated and stainless steel besides marking aluminum. Each custom or standard design has specific attributes and strengths making them ideal for a variety of industrial applications.
